As the development team starts work during the sprint, it realizes it has selected too much work to finish in the sprint. What should it do?
Answers
Answer:
When work is more but time is less
Explanation:
If you consistently modify sprint times, you lose the ability to write stories effectively, manage the backlog, estimate effort and lose personal accountability. The timebox exists for accountability and to help each role learn and develop. if sprint lengths vary it becomes very difficult to measure velocity. it's better to reintroduce unfinished items to the backlog and give the team another chance to select their work. it's a good learning experience.
The Scrum is the focus on people and their behavior. The team selects the work instead of being assigned the work. Plan driven methodologies failed due to a lack of buy-in from team members. The team knows upfront the deadline. If they don't hit their milestones use it to revisit how the work was selected and estimated.
